There is a speed problem on Windows that we know about:
Under *nix, it makes little or no time difference whether I call
gdk_draw_point or segment N times, or whether I call
gdk_draw_points or segments once with N points.
Under Win32, however, the batched calls seem to be about 20 times
faster.
This would not be a problem except that gdk contains these batched
calls only for points and lines, so I'll eventually need to write
them (or find a recruit to write them) for arcs and rectangles.
